5. Safety precautions

5.1 Basic safety instructions

In addition to the safety precautions listed in the individual sections of these operating instructions, the following points must be strictly observed at all times:

5.2 Use as directed

• The tool is intended for professional use by

operators who have received proper instruction on its safe use.

• Manipulation or modification of the tool is not

permissible.

• To minimize the risk of injury, use only original

Hilti fasteners, cartridges, accessories and spare parts.

• Observe the information printed in the

operating instructions concerning operation, care and maintenance.

• Never point the tool at yourself or anyone

else.

• Never cock or depress the nosepiece of the

tool against your hand or any other part of your body

• The tool is designed to drive fasteners into

steel base material only. Do not attempt to drive a fastener into other materials, or into hardened or brittle steel such as welds, cast iron, or spring steel

• The tool and its ancillary equipment may

present hazards when used incorrectly by untrained personnel or not as directed.

• Pull the trigger only when the nosepiece of

the tool has been fully compressed against the base material.

• Always hold the tool securely, and

perpendicular to the work surface. This will reduce the possibility of the fastener ricocheting off the work surface.

• Never redrive a fastener. This may cause the

fastener to break or shatter.

• Always observe the following application

guidelines:

• Min. distance to free edge of base material: 1/4”

• Min. spacing between fasteners: 1“

• Min. base material thickness: 1/8”

5.3 Take the necessary precautions at the workplace

• Ensure that the working area is well lit.

• Objects which could cause injury should be

removed from the work area. Untidiness at the workplace can lead to accidents.

• .

• The operator and all bystanders must wear

eye protection and a hard hat while tool is in use. Ear protection is necessary when working in confined areas.

• It is recommended that protective gloves and non-slip shoes are worn when working outdoors.

• Keep the tool and cartridges locked in a container and in a safe place when not in

use. Keep out of reach of children

• Avoid unfavorable body positions. Work from a secure stance and stay in balance at all times.

• Keep your arms flexed when operating tool (do not stiff arm). If you feel any pain or discomfort, discontinue use.

• Make sure no one stands on the opposite side of the surface where fastenings are being made - a fastener could throughpenetrate and injure someone.

5.4 General safety precautions

• Use the right tool for the job. Do not use the tool for purposes for which it was not intended. Use the tool only as directed and when it is in faultless condition.

• Take the influences of the surrounding area into account. Do not use the tool where there is a risk of fire or explosion.

• Keep the grips clean, dry and free from oil and grease.

• Press the tool against the work surface at right angles (perpendicular to the work surface).

• Never pull back the magazine. Under certain circumstances, this could cock the tool, making it ready for firing. When the tool is ready to fire, the piston or a fastener could be driven inadvertently into a part of the body, or free-flighted.

• Never leave a loaded tool unattended.

• Always remove all cartridges and fasteners

from the tool after work and before carrying out cleaning, servicing or maintenance.

Page 9

• Never compress the tool while manipulating the release catch, as this might result in injuries to the hand of the operator

• Check that moving parts function correctly without sticking and that no parts are damaged. Do not use a tool that is incomplete or does not operate properly.

• Check the tool for possible damage. Protective devices and any parts that may have suffered slight damage should be checked for correct operation and functionality before further use. Damaged safety devices or other damaged parts must be replaced or repaired properly by an authorized repair workshop unless otherwise indicated in the operating instructions.

actuated:

* Keep the tool pressed against the work

surface for 30 seconds.

* If the cartridge still does not ignite,

withdraw the tool from the work surface, taking care that the tool is not pointed at anyone.

* Advance the cartridge strip to the next

cartridge manually (see 7.2.1), and continue to use the remaining cartridges in the strip. Once the magazine/cartridge is removed, dispose of it in such a way that it can neither be used again nor misused.

5.4.1 Mechanical hazards

• Use only fasteners and cartridges that have been approved for use with the tool.

5.4.2 Thermal hazards

• Allow the tool to cool down before servicing or storing.

• Do not exceed the recommended fastener driving rate (1000 fasteners per hour in sustained operation, 1500 fasteners per hour over a maximum of 10 minutes). The tool may otherwise overheat, and could cause the cartridge to ignite.

• An operator should wear gloves if the tool is to be dismantled while it is hot.

5.4.3 Danger of explosion

• Do not attempt to pry or forcibly remove cartridges from the magazine strip or tool – this could cause a cartridge to ignite.

• Unused cartridges must be stored in a dry, high place, locked up or out of reach of children.

5.5 Requirements to be met by users

• The tool is intended for professional use.

• The tool may be operated, serviced and

repaired only by authorized, trained personnel. This personnel must be informed of any special hazards that may be encountered.
